The TV remote control is mainly composed of a microprocessor chip forming a remote control signal, a crystal oscillator, an amplifying transistor, an infrared light-emitting diode and a keyboard matrix.
Its working principle is as follows: The internal oscillator of the microprocessor chip IC1 forms a high-frequency oscillator through pins 2, 3 and the external oscillation crystal X to generate a high-frequency oscillation signal (480kHz). This signal is sent to the timing signal generator to generate 40KHz sine signal and timing pulse signal. The sinusoidal signal is sent to the code modulator as the carrier signal; the timing pulse signal is sent to the control and sweep signal generator, key input encoder and command encoder as the time standard signal of these circuits.
